Three-phase Voltage and Phase-sequence Phase-loss Relay

Do You Face These Problems?

1. Alarms do not occur before equipment is damaged.

2. Protection is necessary because of poor power supply quality overseas.



Our Value Design Products Increase the Value of Your Control Panels. Protect motors and other equipment from unstable voltages in the power supply system. Detect overvoltages, undervoltages, voltage asymmetry, phase sequence, and phase loss for three-phase power supplies.
